CARIBBEAN TIME ZONES
In the Caribbean most nations use one of two time zones. From west to east they are GMT -5 and GMT -4. Areas in the Caribbean which use the GMT -5 time zone correspond with Eastern Standard Time in the United States and Canada. Areas in the Caribbean which use the GMT -4 time zone correspond with the Atlantic Standard Time Zone which is used in Puerto Rico. These corresponding time zones do not always result in the same local time due to daylight saving time not being observed in all locations.
Daylight Saving Time in the Caribbean is used by several countries, including the Bahamas, Bermuda, Cuba, Haiti, and the Turks and Caicos Islands. The beginning and ending times vary for each nation.
